Want a leaner Windows 10 with less telemetry and fewer preinstalled apps? Atlas OS Windows 10 applies a set of performance, privacy, and usability changes to Windows. The project uses AME Wizard and customizable Playbooks to apply those changes.
How does Atlas apply changes to Windows?
Atlas is a modification applied to Windows, not a separately distributed custom Windows ISO. AME Wizard runs the Atlas Playbook, a script-like archive containing the actions that change system settings and components.
The Playbooks are primarily plain text, so their instructions can be inspected. Atlas's changes include removing commonly unneeded apps, configuring interface settings, and disabling advertisements. Apps removed by Atlas can be reinstalled.
Which privacy and security settings can you control?
Atlas removes much of Windows' built-in telemetry and applies group policies intended to limit data collection. Those changes cover Windows itself; they do not govern what a browser or another third-party app collects.
Security options are configurable, with information about the tradeoffs involved. Options include Windows Defender, SmartScreen, User Account Control, CPU mitigations, and core isolation features. Automatic Windows updates can also be toggled.
What should you know before applying Atlas?
The Atlas Playbook works through AME Wizard, whose backend carries out the included actions. Atlas does not change Windows activation. Since security features and Windows Update settings can be adjusted, the choices made during configuration affect which protections and update behavior remain in place.
- You start from a normal Windows installation and apply Atlas on top of it.
- The Playbook is a renamed ZIP archive, with its instructions mainly in plain text.
